Power
The unit draws power from either a direct AC connection or its own rechargeable
battery. To optimize the system’s use of power, enter the Power Managment Menu
in the Setup Menus. (See page 25.)
AC power
We recommend you use the AC adapter whenever possible to provide the unit with
a constant supply of power and simultaneously keep the battery charged. (See
“Charging/discharging the battery” below for details.) The proper method for
connecting the AC power to the unit is shown below:
Battery power
When you first receive the battery, it is installed in the system but not charged. We
recommend that you completely charge and discharge the battery twice as soon as
possible, as this improves the accuracy of the unit’s battery power gauge and
optimizes the battery’s life and performance.
Charging/discharging the battery
The battery must be connected to an AC power source for about 2 and one-half
hours to charge completely. The unit can run on a fully charged battery for about 3-
5 hours of normal use before the battery needs recharging. When the battery level
gets low, the battery icon in the status display bar blinks. (See page 8.)
